Nmap (Part 1 of 4)

This video, presented by instructor Tony Hills from the Cybersecurity Education for Advanced Manufacturing Organizations project, is the first in a series of lectures on using Nmap, a free, open-source network scanning software used in network functionality and security. The video begins by outlining the series' objectives, such as discussing host discovery with Nmap, port mapping, and performing network mapping. This video lays the groundwork for subsequent lessons by providing an introduction to Transmission Control Protocol (TCP) and Internet Protocol (IP) communications. Hills illustrates the layers of the open systems interconnection (OSI) reference model and discusses data headers, Domain Name System (DNS), Address Resolution Protocol (ARP), and more.

This video runs 16:24 minutes in length. Additional videos from the series and a related training scenario are available to view separately.
